OA04.03 Mobocertinib in NSCLC With EGFR Exon 20 Insertions: Results From EXCLAIM and Pooled Platinum-Pretreated Patient Populations

Mobocertinib is a potent first-in-class tyrosine kinase inhibitor (TKI) designed to target EGFR exon 20 insertion (EGFRex20ins) mutations. We report first results from the EXCLAIM extension cohort of a phase 1/2 study (NCT02716116) and results in patients with EGFRex20ins-mutant NSCLC who received prior platinum-based therapy from the dose-escalation/expansion parts of the study and the EXCLAIM extension cohort.
